EVERETT, Wash., April 2, 2024 — Calibration technicians need efficient, reliable oscilloscopes to reduce costly errors, delays, and safety issues. Given the complexity of these scopes – with thousands of test points – operators need […]
March 14, 2024 Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the detection of planets outside of our solar system and high-speed optical […]
by David F. Martson The development and use of intrinsic standards, e.g., Josephson Voltage Standard or JVS, has brought the primary level of uncertainty achievable for DC voltage down to a few nV/V (ppb), while […]
by James G. Salsbury When an accredited laboratory makes a statement of conformity to a specification, ISO/IEC 17025 requires the use of a decision rule that takes into account the level of risk associated with […]
by Dan Wiswell We’ve all heard people speak of accuracies and tolerances in more colorful language than what would be expected in a metrology lab. “Plus-or-minus a hand grenade” or, “Close enough for government work” […]
EMPIR Capacity Building project Traceability Routes for Magnetic Measurements (TRaMM, 21SCP02) is a training project, where INRIM, the NMI for Italy, is transferring knowledge and expertise in the field of magnetic measurements and calibrations to […]
In May 2023, the new research project “Trustworthy virtual experiments and digital twins” (ViDiT) started. ViDiT is a metrology project funded by the European Union. Metrology is the scientific study of measurement focusing on measurement […]
PTB-News 1.2024 – Following a successful pilot phase, accredited calibration laboratories will be able to apply for the digital calibration symbol starting in late March 2024 and thus provide digital proof that they are accredited. […]
